Introduction Pubic lice are parasitic insects that infect human skin and hair. These tiny creatures, measuring only about 2 mm in size, are part of the microcosm and live in crowded places, including hotels, hostels, inns, train compartments and other places where there is a high concentration of human hair. The effectiveness of the use of chemotherapy in the fight against lice has been proven. One of the most effective drugs used to treat this disease is Veda-2 shampoo against lice.
